Series 616W Differential Pressure Transmitter
Specifications - Installation and Operating Instructions
Bulletin P-616W
The
SERIES 616W
Differential Pressure Transmitter senses the pressure of air and
non-combustible, compatible gases and sends a standard 4 to 20 mA or selectable
0 to 5/0 to 10 VDC output signal. All models, including those featuring an LCD, are
factory calibrated to specific ranges. Positive, negative, and differential pressures
can be measured within a full scale accuracy of ±0.25%. This weatherproof unit is
enclosed in a polycarbonate case, rated IP66/NEMA 4X. The span and zero controls
are for use when checking calibration, and are not intended for re-ranging.
